What the best examples of fungi reproduction?
Olenka [21]

Answer:

Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Somatic cells in yeast form buds.

The process of phagocytosis involve all of the following except
evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

  1. activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
  2. chemotaxis  - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
  3. adhesion - the phagocyte attaches to the pathogen.
  4. ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
  5. elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

<u>The</u><u> secretion of cytotoxins</u><u> is not a part of the phagocytosis, and is a process exclusive to </u><u>T cells</u><u> (leukocytes that lack the ability to phagocyte).</u>

Why might having an excretory system that excretes urine be a disadvantage in a desert environment? how can desert animals overc
Pani-rosa [81]
<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration. There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>
